Each of the 20 Sections follows this format: · · · · Clear statement of the problem. Inclusion of suitable graphs and illustrations to clarify the procedure. This relatively simple, yet comprehensive format adds greatly to the use of the Handbook by the engineer or technician.

Each section contains a list of references or a bibliography that is pertinent to the subject matter.

This edition also includes a CD that has calculation procedures available for inclusion of other parameters, which will allow you to calculate problems with your specific numbers inserted.
